DEVICE FOR AUTOMATIC REGULATION, OF OUTLET-SLUICES.

Specification of Letters Patent.

Application filed August 8, 1906. Serial No. 329,670.

T0 (LZZ whom it may concern:

Be it known that I, IGNAZ FRANZ WES- SELY, a subject of the Emperor ofAustria- Hungary, residing at Linz, Empire of Austria-llungary, haveinvented certain new and useful Improvements in Devices for AutomaticRegulation of Outlet-Sluices, ofwhich the following is a specification.

This invention relates to improved means for automatically effecting theopening or closing of an outlet-sluice in accordance with the changes ofthe water-level. This change of the extent of opening of the sluice-gatecan be efl ected either by the upper or the lower water-level, so thatthe water-level in question is maintained constant within small limits,.which need not be considered in prac tice, the result in the case whenthe lower water-level is used to control the sluicergate being that thesame quantity of water is always discharged from the sluice, whatever bethe head.

The device consists of a balanced bellcrank lever controlled by a float,one arm of the said lever being normally in horizontal position, butbecoming inclined under the influence of a float When the water-levelchanges, and thereby switching in a motor operating the driving-gear ofthe sluice, so that the position of the sluice-gate is correspondinglyaltered. By the movement of the sluice-gate the lever is at the sametime brought back again into its normal horizontalposition, owing to thepivot-point of the bell-crank lever being moved in the same direction asthat in which the float has moved under the influence of the change inthe water-level, whereby the motor is automatically switched out.

A constructional form of my improved regulating device is illustrated inthe accompanying drawing.

a is a spindle carrying the driving-gears o w of the sluice-gate z,provided with the rack-bars a; y. b is a worm mounted on the spindle aand engaging with a worm-wheel c. The ratio between the worm and thewormwheel is made so that when the sluice-gate z is moved from one tothe other of its extreme positions the worm-wheel c is turned not quitethrough three hundred and sixty degrees. To the worm wheel c is secureda cam d or the like. In the construction illustrated the said cam d isformed as a spiral flange and passes between two rollers e e on pivotedat f abalanced bell-crank lever, the arm 9 of which carries a float i bymeans of an adjustable rod h. The oscillation of the arm 9 is limited byadjustable stop-screws 7c and Z. The other armmof the bell-crank leveracts on the control-spindle n by means of a follower g. y The spindle nhas mounted on it a grooved disk p, which is connected by a band p witha disk 7%, fast on a driving-shaft 0. Secured to the latter is also adrum 7, which rotates with the shaft 0 and by means of an open belt 1"and a crossed belt r drives two idle pulleys t and a, respectively, theulleys being loosely mounted on the spin le a. Between the two pulleys tand 11, a pulley s is mounted on the spindle a, being secured thereto,whereas on the control-spindle n there is mounted a belt-shifting deviceB, adapted to shift, by means of levers 1 2 3, the belts r and r in awell-known manner.

The working of the device is asfollows: If the water-level remainsconstant, the army of thebell-crank lever'is horizontal, and the arm mkeeps the control-spindle n in such position that the source of power isswitched out. The spindle a therefore stands still, and the pivot-pointf of the bell-crank lever is then a fixed points If the water.-levelchan es, the bell-crank lever is turned by the float i, and thecontrol-spindle n is pushed thereby in one or'the other direction, asthe case may be, whereby either the open belt 1" or the crossed belt ris shifted onto a vertically-guided slide e. 7 On the slide is g thepulley s by means of the belt-shifting device B, which causes thespindle a to be driven in one or other direction. While the position ofthe sluice-gate is changing, the spindle it rotates, and at the sametime the worm and the worm-wheel rotate the cam d, which moves the slide6 in the same direction as that in which the float has been moved. Theslide 6 carries with it the pivot-point f of the bell-crank lever, andas the outer end of the bell-crank lever can be assumed as being fixedby the float the lever-arm g is again set in a horizontal position. Bythis movement of the bell-crank lever the controlspindle n is broughtback to the switchedout position, so that the belt is shifted back ontoits idle pulley, wherebythe spindle a is prevented from furtherrotation, leaving the sluice-gate in the position into which it has beenmoved. I

IIO'

To use the apparatus for maintaining the upper water-level constant, thedevice is set in such manner that when the sluice-gate is completelyclosed the slide a is in its lowest position. The bottom set-screw k isthen set in such manner that the arm g of the bell- 1 .set lever-arm 9.To these two limiting positions of the lever-arm g in its horizontalposition correspond the positions of the sluicegate closer and open, andhigher or lower water-levels than those given by the said limitingpositions can no longer bring about the movement of the sluice. Theautomatic action hereinabove described takes place between these twolimiting positions.

For regulating the sluice-gate to suit the lower water-level the settingof the sluicegate is efi'ected in the same manner, with the difl'erencethat to the bottom limit position of the arm 9 in the horizontalposition will correspond the position sluice open and to the upper theposition sluice closed.

As the height of the lower Water-level depends on the quantity of waterdischarged by the sluice-gate and the said quantity for a given openingof the sluice-gate depends on the head of the dammed water, themaintaining constant of the quantity of water discharged is efl'ected bymeans of the device according to this invention in such manner that thechange of the quantity of water discharged, which is produced by thechange of head or pressure and which again brings about a change in thelower Water leVel, is

neutralized by a correspondingincrease or reduction of the outlet area.

By suitably choosing the dimensions of 1 the float, as Well as thelength of the arms of the bell-crank lever and the distance be-- ingproportions and the size of the motor the sensitiveness of the devicecan be made to suit the requirements of practical working.

I claim 1. In a device for the automatic regulation of sluices, thecombination with the spindle carrying the operating-gear of thesluice-gate, of a slide, means operated by the said sluicegate-operatingspindle for moving said slide in accordance with the position of thesluicegate, a balanced bell-crank lever, pivoted to said slide, a floatconnected to one arm and a control-spindle connected to the other arm ofsaid bell-crank lever, so as to move therewith, and means on saidcontrol-spindle for causing the said sluice-gate-operating spindle to bedriven in either direction.

2. In a device for the automatic regulation of sluices, the combinationwith a spindle carrying the operating-gear of the sluicegate, of aslide, means operated by the said sluice-gate-operating spindle formoving the said slide in accordance With the position of thesluice-gate, a balanced bell-crank lever pivoted to the said slide, afloat connected to one arm and a control-spindle connected to the otherarm of the said 12 ell-crank lever, so as to move therewith, and meanson said control-spindle for causing the said sluicegate-operatingspindle to be driven in either direction, and adjustable stops for thefloatcarrying arm of the bell-crank lever to determine the length of itsmovement in a predetermined position of the sluice-gate.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit- IIGSSGS.
